Revert "Shuffle detection #2064" It causes a serious regression hanging a simple fixed depth search. Reproducible with: position fen q1B5/1P1q4/8/8/8/6R1/8/1K1k4 w - - 0 1 go depth 13 The reason is a search tree explosion due to: if (... && depth < 3 * ONE_PLY) extension = ONE_PLY; This is very dangerous code by itself because triggers at the leafs and in the above position keeps extending endlessly. In normal games time deadline makes the search to stop sooner or later, but in fixed seacrch we just hang possibly for a very long time. This is not acceptable because 'go depth 13' shall not be a surprise for any position. This patch reverts commit 76f1807baa90eb69f66001d25df2a28533f9406f. and fixes the issue https://github.com/official-stockfish/Stockfish/issues/2091 Bench: 3243738
